Current through November, 2024
Section 11-45-141 - Calibration and check of survey instruments
(a) A licensee shall ensure that the survey instruments used to show compliance with this part have been calibrated before first use, annually, and following repair.
(b) To satisfy the requirements of subsection (a), the licensee shall:
(1) Calibrate all required scale readings up to one thousand millirems (ten millisieverts) per hour with a radiation source;
(2) For each scale that shall be calibrated, calibrate two readings separated by at least fifty percent of scale rating; and
(3) Conspicuously note on the instrument the apparent dose rate from a dedicated check source as determined at the time of calibration, and the date of calibration.
(c) To satisfy the requirements of subsection (b), the licensee shall consider a point as calibrated if the indicated exposure rate differs from the calculated exposure rate by not more than twenty percent, and shall conspicuously attach a correction chart or graph to the instrument.
(d) A licensee shall check each survey instrument for proper operation with the dedicated check source before each use. The licensee is not required to keep records of these checks.
(e) The licensee shall retain a record of each calibration required in subsection(a). The record shall include:
(1) A description of the calibration procedure; and
(2) A description of the source used and the certified dose rates from the source, and the rates indicated by the instrument being calibrated, the correction factors deduced from the calibration data, the signature of the individual who performed the calibration, and the date of calibration.
(f) To meet the requirements of subsections (a), (b), and (c), the licensee may obtain the services of individuals licensed to perform calibrations of survey instruments. Records of calibrations which contain information required by subsection (e) shall be maintained by the licensee.
